# Authorship segmentation on MAS (entire corpus) Source: [Authorship segmentation on MAS (entire corpus)]() Collection index: [llms.txt]() Data updated: 2026-02-26T06:02:47.253Z Evaluation of Authorship Segmentation performance across the entire corpus of the MAS dataset. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Authorship segmentation | | Dataset (including any stated split) | MAS (entire corpus) | | Metric | SBDA @ 0.3 | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 18 of 18 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [SBDA @ 0.3](): Higher is better; unit: PERCENT. - [SBDA @ 0.5](): Higher is better; unit: PERCENT. - [SBDA @ 0.7](): Higher is better; unit: PERCENT. - [SBDA @ 0.9](): Higher is better; unit: PERCENT. - [Seg Precision @ 0.3](): Higher is better; unit: PERCENT. - [Seg Precision @ 0.5](): Higher is better; unit: PERCENT. - [Seg Precision @ 0.7](): Higher is better; unit: PERCENT. - [Seg Precision @ 0.9](): Higher is better; unit: PERCENT. ## Recorded results | Method | SBDA @ 0.3 | Result date | Report paper | | --- | --- | --- | --- | | RoBERTa + ModernBERT + CRF\* | 45.7 | Not recorded | 69326709d6b0dd334293429f | | ModernBERT + BiGRU + CRF\* | 41.9 | Not recorded | 69326709d6b0dd334293429f | | RoBERTa + BiGRU + CRF\* | 41.6 | Not recorded | 69326709d6b0dd334293429f | | ModernBERT + CRF\* | 41.3 | Not recorded | 69326709d6b0dd334293429f | | DeBERTa + BiGRU + CRF\* | 39.8 | Not recorded | 69326709d6b0dd334293429f | | DeBERTa + CRF\* | 38.7 | Not recorded | 69326709d6b0dd334293429f | | RoBERTa + CRF\* | 32 | Not recorded | 69326709d6b0dd334293429f | | SeqXGPT | 31.5 | Not recorded | 69326709d6b0dd334293429f | | SpanBERT | 29.4 | Not recorded | 69326709d6b0dd334293429f | | Binoculars | 28.5 | Not recorded | 69326709d6b0dd334293429f | | BiLSTM+CRF | 26.1 | Not recorded | 69326709d6b0dd334293429f | | FastDetectGPT (gpt-neo-2.7b) | 25.9 | Not recorded | 69326709d6b0dd334293429f | | FastDetectGPT (falcon-7b-instruct) | 25 | Not recorded | 69326709d6b0dd334293429f | | GPTZero | 22.3 | Not recorded | 69326709d6b0dd334293429f | | Glimpse (davinci-002) | 21.4 | Not recorded | 69326709d6b0dd334293429f | | Glimpse (baggage-002) | 20.8 | Not recorded | 69326709d6b0dd334293429f | | logp(x) | 15.3 | Not recorded | 69326709d6b0dd334293429f | | entropy | 15.1 | Not recorded | 69326709d6b0dd334293429f | ### RoBERTa + ModernBERT + CRF\* SBDA @ 0.3: 45.7.
